Title:
DISPOSAL METHOD AND EQUIPMNT FOR EXHAUST GAS FROM COMBUSTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/061107
Kind Code:
A1
Abstract:
The invention aims at separating carbon dioxide from exhaust combustion gas effectively and making it possible to discharge the residual exhaust combustion gas enriched in the exhaust gas components other than carbon dioxide by the separation of carbon dioxide into the atmosphere. Air (7) is separated into oxygen (9) and a nitrogen-base gas (10a) in an oxygen separator (8); coal (1) is burnt with the oxygen (9) in a burner (5a) in a combustion furnace (4); an exhaust combustion gas from the furnace (4) is subjected to exhaust gas treatment; a part of the resulting exhaust combustion gas is recycled to the burner (5a), while the remainder is compressed: the carbon dioxide (29) liquefied by the compression is taken out, while the residual exhaust gas component (31) which is not liquefied by compression is mixed and diluted with the nitrogen-base gas (10a) obtained by separating the oxygen (9) from the air (7) in the oxygen separator (8); and the diluted exhaust gas is discharged into the atmosphere.
